Article Summary

Synthetic resins start out as viscous liquids that eventually solidify or "cure" into clear or translucent solids. These materials, which combine the desirable properties of strength, durability and light weight, are so useful that you can find them in thousands of applications, particularly aircraft, automobiles and electronic circuits. But for all that versatility, there's one thing that's remained elusive: once cured, resins can not be reshaped. Now, a team from France's National Center of Scientific Research (CNRS), led by award-winning physicist Ludwik Leibler, has developed an inexpensive and easily-produced material that is not only reshapable (like glass), but also repairable and recyclable, again, like glass. That's a potential boon for the auto body industry alone, and the possibilities for other uses are seemingly endless.
